How can I create a development version of my multisite?

Hello,
I am running a multisite installation on my VPS (mainly for developer/designer purposes) I am curious what the recommended method is for making a development version of my multisite? Is it possible to move the entire multisite using Snapshot? I have read around the blog here and found that some users have had success moving single sites but I haven't found information from users experience moving an entire multisite with snapshot.

Thank you to the entire WPMU Dev crew for the amazing services and resources that you are providing here. I have learned so much and come so far with the help of WPMU Dev.
